KEY TAKEAWAYS •
Glycolysis is an evolutionary older metabolic pathway that takes glucose and turns it into pyruvate and energy.
•
The point of the Krebs cycle and glycolysis is to make energy-storing molecules that go on to drive the process that makes ATP energy.
•
A fully-oxidized or metabolized glucose molecule goes on to make CO2, water, and energy.
•
Fermentation involves making energy without the use of oxygen.
•
Photosynthesis takes light energy and turns it into temporary energy-storing molecules that are used to drive light-independent pathways in the plant cell.
•
Light-independent pathways in plants will fix carbon from carbon dioxide to make sugars.
